ABSTRACT:
A method and system for providing enhanced diagnostic ability for monitoring vehicle performance characteristics includes utilizing a combination of temperature and lubrication level information. A first sensor monitors the temperature of a selected component, such as an axle, while a second sensor detects an amount of lubrication associated with that component. An electronic controller utilizes the temperature and lubrication level information to determine a performance characteristic and determines whether the selected component is operating within an acceptable range. The electronic controller preferably provides information to a vehicle operator through an on-board display indicating the monitored and determined characteristics on a real-time basis. Additionally, the electronic controller includes a memory module that stores performance characteristics information over time so that information can be provided to a service technician utilizing an external diagnostic computer.
